ADHD Medication Linked to Reduced Risk of Substance Misuse, Suicide, and Accidents
Newly diagnosed ADHD patients who begin taking medication, particularly methylphenidate (Ritalin), within three months of their diagnosis experience a significantly lower risk of serious negative outcomes like substance misuse, suicidal behavior, and traffic accidents, according to a study published today.
Researchers from the Karolinska Institute in Stockholm, Sweden analyzed data from 148,581 patients aged 6 to 64 who received an ADHD diagnosis between 2007 and 2018. The study, published in the British Medical Journal, found that approximately 57 percent of patients initiated drug treatment within three months of diagnosis, with methylphenidate being the most commonly prescribed medication in 88 percent of those cases. This finding is particularly important as ADHD is increasingly recognized as a lifelong condition impacting a growing number of people.
Medication was shown to reduce the risk of first-time substance misuse by 15 percent and recurrent misuse by 25 percent. First-time suicidal behavior decreased by 17 percent, with subsequent attempts reduced by 15 percent. Criminal behavior, both initial instances (13 percent reduction) and repeat offenses (25 percent reduction), also saw significant declines. Furthermore, the risk of first-time traffic accidents was lowered by 12 percent, and recurrent accidents by 16 percent. “Oftentimes there is no information on what the risks are if you don’t treat ADHD,” explained study author and psychiatrist Samuele Cortese, from the University of Southampton. “Now we have evidence they [ADHD medications] can reduce these risks.” You can learn more about ADHD from the Centers for Disease Control and Prevention.
Globally, around 5 percent of children and 2.5 percent of adults live with ADHD, and untreated symptoms can significantly impact daily life. Researchers emphasized the need for continued monitoring and individualized treatment plans, and stated they will continue to investigate the long-term effects of early intervention with medication.
